Citrix Exam 1Y0-440 Topic 7 Question 54 Discussion

Scenario: Based on a discussion between a Citrix Architect and a team of Workspacelab members, the MPX Logical layout for Workspacelab has been created across three (3) sites.

They captured the following requirements during the design discussion held for a Citrix ADC design project:

All three (3) Workspacelab sites (DC NDR and DR) will have similar Citrix ADC configurations and design

Both external and internal Citrix ADC MPX appliances will have Global Server Load Balancing (GSLB) configured and deployed in Active/Passive mode

GSLB should resolve both A and AAA DNS queries.

In the GSLB deployment the NDR site will act as backup for the DC site, whereas the DR site will act as backup for the NDR site

When the external Citrix ADC replies to DNS traffic coming in through Cisco Firepower IPS the replies should be sent back through the same path

On the internal Citrix ADC. both front-end VIP and back-end SNIP will be part of the same subnet

USIP is configured on the DMZ Citrix ADC appliances

The external Citrix ADC will act as default gateway for back-end servers.

All three (3) sites (DC, NDR, and DR) will have two (2) links to the Internet from different service providers configured in Active/Standby mode

Which design decision must the architect make to meet the design requirements above?
